Andersen-Tawil syndrome: symptoms

Andersen-Tawil syndrome is outlined by 3 main options (i.e. a clinical triad), specifically periodic palsy, arrhythmias and heart abnormalities, and distinctive physical options. However, the disorder is extremely variable and not all affected people can develop all 3 of those characteristic symptoms. Andersen-Tawil syndrome will vary greatly in expression and severity from one person to a different, even among members of a similar family.

Although researchers have established a transparent syndrome with characteristic or “core” symptoms, abundant concerning the disorder isn't absolutely understood. many factors as well as the little range of known cases, the dearth of huge clinical studies, and also the chance of different genes influencing the disorder forestall physicians from developing a whole image of associated symptoms and prognosis. Therefore, it's vital to notice that affected people might not have all of the symptoms mentioned below. folks ought to seek advice from their children’s medico and medical team concerning their specific case, associated symptoms and overall prognosis.

Generally, {this could|this might|this could} not cause any symptoms (asymptomatic) or may cause shortness of breath or palpitations. In some cases, these arrhythmias could cause episodes of fainting or loss of consciousness (syncope). In severe cases, the chance of cardiopulmonary arrest and overtime exists. though overtime thanks to the internal organ abnormalities has occurred in Andersen-Tawil syndrome, it's extraordinarily rare.
